TR Multicoax Series | Quantum Computing
Description
The newest form factors of Ardent’s TR Multicoax connectors support
the many unique challenges of Quantum Computing applications.
Density, substantial environmental changes, and an increasing needfor more high-speed lanes are causing quantum computer designers
to rethink traditional routing methods of individual cables. By utilizing
superconducting materials like CuNi cables and the existing patented
contact technology Ardent is known for, engineers will be able todrastically decrease real estate required by individual connectors andincrease their channel count while improving signal integrity in theirsystems.
Key Benefits• Feedthrough offers leak-proof design (Max leak rate 2.00E-09 LTorr)• Variety of coaxial cable materials available (Flexible, CuNi, NbTi)• Extremely dense form factor (168+ channels in standard ISO disc)• Easily mate/de-mate multiple high-speed lanes
